Curved Shapes Workbench

[christi]

maybe an option to give the size of hull for scale factor instead the bounding box of the whole hull curves could avoid that?

I think this will make my tool too complicated

I updated fcad on my mac and when I load an example file from the forum, I get this errors in report view:

Ha ha.. I thought by now, you would have finished this plane. I am trying to learn somethings but I upgraded my home computer to OSX Monterey and now I have issues with the Curves WB. I got these same errors when I opened your new Sirius_2009-Wing_vb file. I really think the system upgrade broke/changed some python things but I do not know how to fix.

Thank you so much christi for the Notch Tool.

I have difficulties using it.
When I do the Notch the parts turn 90 degres............

Your design was created with an older version of the CurvedShapes workbench. Delete and re-create the Curved Array parts to get them updated.

It seems that the algorithm to find out the cut direction does not work. Since I have not found a solution for this, you can manually change the parameter Cut Direction in your design. Set Cut Direction to 0,0,1 for the first NotchConnector and 0,0,-1 for the second. Enter the z value first, because 0,0,0 will again evaluate to the wrong values.

I found a better solution for the CutDirection finding algorithm. Please update the workbench and try again.

Can anyone help what could be the problem? The CurvedArray object looks like no problem at all, but I cant use the model for further work.

Thanks,

Meanwhile I carried out a different test:
Symptoms are the same on a different fresh system.
